A signage with an area of ​​about 5 meters by 3 meters is erected on the edge of the fairway, 2.7 meters above the ground. The sign is covered with a reflective film. In the evening, the font on the sign will emit white light, and the light source will come from the top of the sign. Block solar panels. Recently, this self-developed solar active luminescent signboard developed by the fairway department of the city was put into use on the Suxi line channel, and it was like putting a “reflective vest†on the fairway to guide the safe navigation of ships at night.
According to Chen Guangjie, chief of the Department of Navigation of the Municipal Waterway Administration Division, under dark night conditions, there is no obvious reference object and can not see the shoreside signage, which is a problem often encountered by ships during the night flight. The solar active luminescent sign can provide clear navigation information for passing occupants in the case of poor dimming distance at night, which facilitates safe navigation of ships at night. The solar active luminescent sign put into use in the navigation route of the Suxi line is also the first active luminescent signage of the inland waterway in the province. The principle is very simple. Solar panels are used to store power during the day and emit light at night.

The reporter saw that the sign was set on the right bank of the Suxi line channel 80 meters from the Wufu Bridge. It marked the route to Wuxi and Wujiang. It will be seen from a distance, the white frame on the green background is white, and the column is diagonal red. In the white and white, there are five groups of ten solar panels at the top of the signboard. “After it is full, it can last 18 days. Even if it encounters cloudy days, there is no problem.†Chen Guangjie said that the signage area is 4.95 meters by 3.3 meters. Covers 3M engineering-grade reflective film, the bottom edge is 2.7 meters from the ground, the pointing distance is 200 meters, the angle between the card face and the centerline of the fairway is 80 degrees, and the face font size is 60cm x 60cm. . "The line of sight 200 meters refers to the visible distance during the day, but in the evening, the line of sight is further away."
This solar active light-emitting sign seems simple and the cost is not small, "a piece will be 100,000 yuan," Chen Guangjie said, next, they will conduct data collection and collect the views of the boat people, comprehensive assessment of the sign of the technical parameters and cost-effective, " If feasible, it will be gradually promoted to other waterways in the urban area to facilitate more ships."
